Thanks for the reminder, it indeed slipped my mind.

As Python features are luckily mostly platform independent, I am not 
sure if a convenient 'platform requirement check' module would be worth 
the energy creating it, any thoughts on that?

For clarity purpose I re'added (and adapted) in what lines I was thinking:
test = RequirePlatform(do_not_raise=True)
# If do_not_raise is not set or False, an error will be raised
# after a failed require line, otherwise just continue.

test.require(key='test1', platform='freebsd', version_min='2.2')
# If the platform is anything else but FreeBSD 2.2 onwards return False
# and store the result of the test.
# Result of the require (and any additional tests
# can be accessed using the index operators;

if test['test1']:
Other requirements like architecture, python vm type/version, cpu 
features, etc. Might also be nice to have.
